Rotatable Relay Antenna for Wireless Backhaul Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional relay antennas in wireless communications networks face inefficiencies in scanning the maximum coverage area in a short time, leading to suboptimal connectivity due to issues like pole shadowing, where antennas either take longer to scan a greater area or fail to scan adequately.
Innovation Solution
Incorporating a rotatable mechanism, such as a motor, into relay nodes with antennas to adjust and reposition them based on control parameters, allowing for a 360° scan to identify and connect to the optimal base station by determining scanning parameters like beamwidth, rotation angle increment, and rotational steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the antenna scans a greater coverage area, then the connectivity and coverage are improved, but the scanning time increases
Solution Approach 1:
The patent applies dynamics by making the antenna rotatable rather than fixed, allowing it to change its scanning area dynamically. The antenna can rotate to scan different coverage areas adaptively, enabling the system to optimize between scanning time and coverage area based on network conditions and requirements.
2Productivity
If the antenna scans faster, then the scanning time is reduced, but the coverage area scanned is limited
Solution Approach 1:
The rotatable antenna mechanism enables dynamic adjustment of scanning speed and coverage area. The system can rotate the antenna to expand coverage when needed or scan faster in limited areas when productivity is prioritized, resolving the contradiction between scanning speed and coverage area.
3Device complexity
If the antenna is fixed in position, then the device complexity is reduced, but the ability to scan maximum coverage area is limited
Solution Approach 1:
By introducing a rotatable mechanism, the patent transforms a static antenna system into a dynamic one. This adds moderate complexity but enables the antenna to scan maximum coverage area by rotating to different positions, effectively resolving the contradiction between device simplicity and coverage capability.

AI summary
Systems and methods are provided for optimizing a relay node in a wireless communication network. A plurality of base stations may be provided as well as at least one antenna at a relay node, the antenna operably coupled to a rotation mechanism. The plurality of base stations can be scanned by the antenna, the scanning using one or more control parameters dictating a portion of a scanning process. Based on the scanning, an optimal base station may be determined and/or an optimal antenna position may be determined. The antenna can adjust to the optimal position and/or can attach to the optimal base station to provide an optimal backhaul link.
